Yet most people in Northern Ireland still seem to want to remain part of the United Kingdom. A BBC poll earlier this year suggested that just 17% of people in Northern Ireland want to leave the United Kingdom.
Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO 2.The liquid carbon dioxide is injected into either a block press or pelletizer. These dry ice production machines have chambers in which, once released to atmospheric pressure, the liquid carbon dioxide converts to dry ice snow and carbon dioxide gas.he carbon dioxide gas is pressurized and cooled to form liquid CO 2.

The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Earth's surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases.
